SPECIFICATION forming part of Letters Patent No. 633,132, datedSeptember 19, 1899. Application filed December 30, 1898. $erial No.700,720. (No model.)

To all whom it may concern:

Be it known that I, ASA W. GRIFFITH, a citizen of the United States ofAmerica, residing in the city of \Vilmington, in the county of NewCastle, in the State of Delaware, have invented a certain new and usefulImprovement in Rest-Plates for Railway-Rails, of which the following isa true and exact description, reference being had to the accompanyingdrawings, which form a part thereof.

My invention relates to the construction of rest-plates forrailway-rails, and has for its object to improve the construction ofsuch plates as heretofore made, particularly in pro viding them withWater shedding flanges adapted to keep the water out of contact with.the gripping-flanges of the plate and in providing them withangularly-set grippingflanges of a peculiar form at once' efficient inholding the plate in place and of a character which can be readily andconveniently made.

The nature of my improvements will be best understood as described inconnection with the drawings in which they are illustrated, and in whichFigure 1 is a cross-section through a rail and tie, showing therest-plate in position between them. Fig. 2 is a plan View of myrestplate viewed from the bottom. Fig. 3 is a cross-sectional view takenon the line 3 3 of Fig. 2, and Fig. t is an end sectional view of aportion of a somewhat modified form of restplate.

A indicates the tie, and B the rail.

0 is the rest-plate, formed, as shown, with spike-holes O 0, extendingthrough it, and with tie-gripping flanges D D, &c., the outermostflanges being distinguished by the symbol D. I propose to make myrest-plate out of wrought iron or steel and by the action of rollsadapted to form at the same time the plate and flanges, and preferablylong bars will be rolled into the cross-sectional form of the rest-plateand then out into sec-' tions, forming the individual rest-plates. Theflanges D D will therefore for convenience of manufacture be madeparallel to each other and especially the lines of junction indicated atd between theflanges and the under side of the plate will be parallel.For certain purposes, however, it is preferable that one or more of theflanges should be set so as to give it a slight angle to the center lineof the tie, which substantially corresponds with the direction of thefiber of the wood, and I therefore bend some of the flanges D abovetheir line of junction with the plate, so that they will run at an angleto instead of parallel to each other. Thus, as shown in Fig. 2, theouter flanges D D have their points d curved outward at the center, andthis is my preferred construction, and is a construction, moreover,which can be readily secured in manufacture by the simple process ofbending the outer flanges outward at the center.

In order to keep water on rainy days from coming readily into contactwith the outer flanges D and finding its way into the grooves formedinthe tie by said flanges, I make my rest-plate with laterally-extendingflanges E E, extending beyondthe outer biting-flanges D and formed withdownwardly-extending lips E from which the water falling on the platewill drip instead of running under the flange and finding its way intocontact with the biting-flange. Preferably I make the under side ofthese water-shedding flanges E lie in a plane somewhat above the planeof the under side of the plate proper, as is indicated, for instance, atE in Fig. 4, andpreferably, also, I chamfer the upper face of theflanges E, as indicated at E, so as to provide an inclined surface downwhich the water on the plate will flow over the water-sheddin g flange Ewith its downwardly-extendinglip E. It willbe obvious that this inclinedwater-shed will tend to draw the water from the adjacent level parts ofthe plate and insure that most of the water falling on its surface shallleave it at its flanged ends and not at its unflanged ends. While Iprefer to chamfer the tops of the flanges E, as above described, careshould be taken not to abridge the flat bearing-surface of the plateproper, which is essential to the provision of an adequate and firmbearing for the rail, and therefore I only carry the chamfers backtolines lying above the flanges D D.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A rest-plate for rails having flanges, as D D, for engaging the platewith a tie and lateral water-shedding flanges E with downwardly-turnededges E extending beyond the outer flanges D.

2. A rest-plate for rails having flanges, as D D, for engaging the platewith a tie and lateral water-shedding flanges E with downwardly-turnededges L and their lower faces E lying in a plane above that of the underside of the plate proper extending beyond the outer flanges D.

3. A rest-plate for rails havinga flat upper face and flanges, as D andD, extending from its lower face and water-shedding flanges E extendingfrom the edges of the plate beyond the outer flanges D said flangeshaving their top faces E chamfered from a line lying substantially abovethe said outer flanges D.

l. A rest-plate for rails having aflat upper face and flanges, as D andD, extending from its lower face and water-shedding flanges E extendingfrom the edges of the plate beyond the outer flanges D said flangeshaving their top faces E chainfered from a line lying substantiallyabove the said outer flanges D and their outer lower edges E turneddownward. l

5. A rest-plate for rails having two or more down \vardly-extending anddown wardly-tapering flanges D D each of uniform cross-sectionthroughout, the lines of junction (1 of said flanges with the plateproper being parallel and one or more of said flanges having its ortheir points or edges d bent at the center to one side only and so thatthe points or edges (1 will at each side of the center of the plate runat diverging angles to the lines of junction (1.

(i. A rest-plate for rails having two or more downwardly-extending anddownwardly-tapering flanges D D each of uniform cross-sectionthroughout, the lines of junction 01 of said flanges with the plateproper being parallel and two of said flanges having their points oredges D bent at their center in 0pposite directions and each to one sideonly substantially as and for the purpose specified.

7. The combination with a rail and wooden tie of a rest-plate 0 havingflanges D D projecting into the fiber of the tie and lateralwater-sheddingflangesE formed with a do\vnwardly-turned outer edge E ASAXV. GRIFFITH.
